A term used to describe advanced, highly precise methods of measuring visual field sensitivity (thresholds) that often leverage sophisticated mathematical models (like Bayesian statistics) and high-density stimulus placement to map the visual field with greater detail than standard perimetry.
read more about quantum visual field mapping ...Standard visual field testing (perimetry) uses a limited number of test points. Quantum mapping increases the number of points and uses adaptive algorithms to more accurately determine the absolute threshold of light detection.
Primarily used in research and highly specialized clinics to track subtle, early progression of visual field loss in diseases like glaucoma, where detecting small changes is critical.
Provides a more sensitive, point-by-point map of the retina's ability to detect light (retinal sensitivity), which can reveal patterns of damage before they are apparent with conventional methods.
While some Octopus perimeters use sophisticated algorithms, 'quantum' typically refers to the next generation of highly detailed, statistical mapping methods rather than the specific brand of perimeter.
Visual field sensitivity is usually measured in decibels (dB), where higher dB means greater sensitivity (detecting dimmer light).
Glaucoma causes localized, patchy damage to the optic nerve fibers. High-resolution mapping allows clinicians to monitor damage to specific bundles of nerve fibers over time.
